About Aftermarket manuals on Manuals.plus

The term Aftermarket refers to a broad classification of spare parts, accessories, and components manufactured by companies other than the original equipment manufacturer (OEM). This category encompasses a diverse range of products, including automotive upgrades like Android infotainment systems, LED lighting, and engine components, as well as replacement parts for small engines, home appliances, and specialized electronics like Starlink mounts.

These products are produced by various independent manufacturers and are designed to offer compatible, often cost-effective alternatives to factory-original parts. Because "Aftermarket" is a descriptor rather than a single corporate entity, specific specifications, warranty terms, and support procedures vary depending on the actual manufacturer or retailer of the specific item.
